EGG-PRESERVING SAFE.

SPECIFICATION forming part of Letters Patent No. 699,418, dated May 6, 1902.

Application filed September 23, 1901. %erial No. 76,192. (No model.)

Te all whom it may concern:

a citizen of the United States, residing at Sacramento, county of Sacramento, State of Cali fornia, have invented an Improvementin Egg- Safes; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to a containing device for eggs and a means for turning and refrigerating the same. I

It consists in details of Construction, which will be more fully eXplained by reference to the acconpanying drawings, in which- Figure 1 is a View of the apparatus. Fig. 2 is a top View of the same. Fig. 3 is a vertical section on line w x of Fig. 2.

The object of my invention is to provide an apparatus in which a large quantity of eggs may be contained in individual Compartments and to so mount said apparatus that it can be revolved at intervals, so as to prevent the yolks of the eggs from settling to one side,

and in conjunction therewith a means for introducing and circulating cold air for the purpose of reducing the temperature and maintaining it at a low degree.

As shown in the acconpanying drawings, A is an exterior case, having the interior com partment boxes or cases 2 separated by an open channel or space, as at 3, and having similar open channels or spaces 4: between the sides of the outer and inner cases and also between the ends thereof. The inner cases 2 are provided with separate compartments, made of pasteboard or other similar or well known material, so that eggs can be placed in the conpartments until the cases are full,each egg having its own individual compartment, within which it is held in position and separated from all the others. The outer case is provided with trunnions 5 at opposite ends, and these trunnions are j ournaled and turnable in the uprights 6 of asuitable framework, so that the cases when 'filled and the outer conpartment in which they are contained may be revolved upon the trunnions. After the inner cases have been filled a cover 11 is.`

The device thus mounted may be revolved by hand orby any suitable device, so that the eggs can be turned at intervals, and the eggs being turned with the case will present different sides uppermost at each point of the revolution, and the yokes Will thus be prevented from settling to the bottom and the eggs from deterioration on this account.

In order to preserve the eggs at a low temperature, the shaft or trunnion 5 at one end is made hollow and is connected by a suitable coupling with an induction pipe or hose 7. This may be connected With any source from which cold air can be obtained, and any air-forcing nechanism (not here shown) may be employed to produce a current of air either continuous or intermittent.

In order to properly circulate the air through the apparatus, I have shown gates 8 and 9 at opposite ends of the outer casing and so arranged as to stand diagonally between the outer casing and the angles of the nnercases 2. These gates are soplaced that air enteringthrough` the inlet shaft or trunnion 5 is diverted by the gate 8 and caused to pass around the outside of one of the boxes 2, be-

tween it and the walls of the outer case. Thence at the opposite end the gate 9 again directs 'the air so that it passes through the channel 3 between the cases 2, and arriving atthe inlet end the position of the gate is such that the air is again diverted around the second box 2 and through the passage 4,

between it and the outer case, finally arrivovercome by that which forces the air into the apparatus, so that ,theair can be readily changed Within'the apparatus at any time, the pressure being sufficient to open the Valve 10 and allow the air within the case to be displaced by the fresh air which is being introduced.

As the cases are made of Wood or some nonconducting material, it will be obvious that IOG time, and when the temperature begins to rise a fresh ch'arge can be intreduced, expelling that which s already in the case through the valve-opening at lO, the latter clesing whenever the pressure at the inlet end ceases.

Having thus described my inventien, what I claim, and desire to secure by Letters' Patent, is-

1. The combination in an egg-safe of an outer case having journal-shafts at the center of its ends and supports therefer, interier cases having individual cempartments adapted te contain eggs er the like said in ner cases separated fren each other and from the inner Walls of the enter case te form intermediate channels, and means Whereby air may be intreduced and circulated through said channels.

2. The cembinatien in an egg-safe of an outer case having tubular shafts or journals at the center of its ends, and supports upon which they are turnable, interier cases hav ing individual cempartments adapted te centain and separate the eggs er thelke, said interier cases separated from each other and from the euter case te form channels between the interier cases and between them and the euter case, and gates whereby the air admitted te said Channels is diverted and caused te pass around, the inner cases between the inlet and outlet passages.

3. An apparatus for containing and preserving eggs and the like, censisting of an exterier case, having tubular jeurnals centrally fixed te the eppesite ends, supports therefer, interier cases separated from each other and from the euter case te form channels er spaces between said interier cases and the euter case, said interier cases having separate compartments in which the contents are placed, neans whereby air may be intreduced through ene ef the hollow journalshafts, a valve-centrolled exit and gates interpesed between the inner and euter cases whereby the current ef air is directed successively around the interier cases.

In witness whereefI have hereunte set my hand.
